cinder安装存在问题，无法创建卷

按照官网安装openstack的pike版本，在cinder安装部分出现问题
控制节点上安装了cinder-scheduler和cinder-volume，重启服务后，状态为up
+------------------+------------+------+---------+-------+----------------------------+
| Binary           | Host       | Zone | Status  | State | Updated At                 |
+------------------+------------+------+---------+-------+----------------------------+
| cinder-scheduler | node-5     | nova | enabled | up    | 2017-11-10T12:52:10.000000 |
| cinder-volume    | node-5@lvm | nova | enabled | up    | 2017-11-10T12:52:12.000000 |


在horizon上执行创建卷的操作，显示错误， cinder-volume.log 和cinder-scheduler.log的信息如下：

可以尝试通过命令行来完成。
